KDL Panic after lots of vm_page_fault

Description
As a developer of Free Pascal compiler
I am using a Haiku VM to check state of Haiku port of this compiler.
I run nightly tests.
But sometimes the VM crashes, usually after a long series of vm_page_fault due to a test program doing an infinite recursion and thus overflooding the stack area.
I was not able to saved the syslog, but managed to create a few
snapshots with syslog output after reboot.

The problem seems to arise every few days (maybe a week in average)
on a virtual box running nightly testsuite of free pascal.
The main cause of troubles seems to be a failure of one of the tests,
tstack.pp
http://svn.freepascal.org/cgi-bin/viewvc.cgi/trunk/tests/test/tstack.pp?view=markup&pathrev=4565
This test generates on purpose (to check that the exception is correctly handled
by Free Pascal Run Time Library)
but (the RTL is probably faulty here)....
the test leads to an endless series of Kernel generated SIGSEGV.
The kernel crash seem to always follow that problem.

Pardon my ignorance, but I have never used FreePascal before. Where do I get it? How can I run the test suite?

Free pascal is a freeware pascal language compiler also available for Haiku.
The source file tstack.pp attached above is the source of the problem.
Nevertheless, compiled with latest release (compiler version 2.6.0),
the test ends as expected with a Run Time Error.
Only with a trunk or fixes compiler or the beta version
available at ftp://ftp.freepascal.org/beta/2.6.2-rc1/i386-haiku, the problem shows up.
Would you be interested in a compiled binary presenting the problem?

Replying to fpcmuller:
Would you be interested in a compiled binary presenting the problem?
That would probably be easiest :) Would such a binary require any additional libraries beyond what comes with the OS?

Endlessly running executable attached, the list of library loaded,
as shown by GNU gdb only lists: runtime_loader, libroot.so,; libnetwork.so, libbe.so and libstdc++.hrev4.so

Please note that I am not sure that runnning this single file is enough to generate the kernel problem, the problem always happened within the long testsuite.
Pierre, how reproducible is this problem for you? And how exactly do you reproduce it? Could you give a short step-by-step description (ie. a package to download, what commands to execute, etc.)? I would love to find another problem causing this bug.
